Table 16 Attributes available for use in analysis queries: CPU Tab (continued)

Processor speed: The clock frequency of the
system's processor.

Proc Speed (GHz)

CPU Capacity

The number of physical (not logical) processor
cores that are active on the system.

Core Count

The headroom percentage indicates how much
the demand for the CPU could grow before
violating the system's CPU utilization limits.

This metric is capped at 3100% to avoid
dividing by zero or other small numbers.

CPU Headroom (%)

Indicates if the system has hyper-threading
enabled (true), or disabled (false).

Hyper-Threading

The percentage of valid CPU samples during
the selected interval. Data points can be invalid
if:

The system is down and data cannot be
collected from it.

The CMS is down and cannot collect any
data.

Data was collected, but a user marked the
data as invalid.

% CPU Valid

Details about the processor hardware, as
provided by the operating system. For
example, Intel Itanium 2 processor.

Table 17 Attributes available for use in analysis queries: Memory Tab

Description

Attribute Name

Section

The percentage of available memory used by
the systems, measured in GB.

NOTE:

The memory attributes only measure

memory that is used by the applications
running on the system. Memory used by the
kernel and disk cache are not included.

Avg Memory (%)

The amount of actual memory used by the
systems, measured in GB. Memory used by the
kernel and disk cache are not included.
